There is also disincentive in +1ing a change that you don't understand 
and is wrong and then a core comes along and -1s it (you get dinged for 
the disagreement). And there is disincentive in -1ing a change for the 
wrong reasons (silly nits or asking questions for understanding). I ask 
a lot of questions in a lot of changes and I don't vote on those because 
it would be inappropriate.

I also notice when "newcomers" are asking good questions for 
understanding and not voting on them, it shows me they are trying to 
learn and are getting invested in the project, not just trying to pad 
stats. Those are the people we look to mentor into bigger roles in the 
project team, be that working on subteams or eventually looking at for 
the core reviewer team.
